Re: [Electric Boats] Re: New member, new electric & solar powered motorboat

 

Those panels are only 18% efficient  you have to have TWO 50w 30x20 inch panels to equal 100watts. So a total of 60x20 inch.    The panels Myles posted are 20% efficient and are made from top of the line cells. 100w = 41x21 inch.  My only fear with the flexible panels is will the plastic membrane discolor over time.  Glass my be heavy but it does stay clear.  Still the weigh savings is nice.  I am thinks of ordering a few of the Sacred solar panels to see what they really look like up close.

g. 100w at 40x32inch, and 200w at the same size.. I was only looking at the latter ones, they seemed very efficient at that size...
